VALVE MECHANISM FOR SIPHON-VALVES OR DRAFT-TUBES.

SPECIFICATION forming part o f Letters Patent No. 678,841, dated July 16, 1901. Application filed December 31, 1900. Serial NO- 411633- (NO model- T all whom it may concern.-

Beit known that I, JOHN P. MACLEARN, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Valve Mechanism for Siphon-Valves or Draft-Tubes, of which the following is a specification.

My invention consists of an improved valve structure designed particularly for use in illing Siphon-bottles.

My improved apparatus comprises means for packing the siphon-nozzle as the valve for admitting the fluid under pressure to said siphon is opened. I may also use the apparatus as a draft-arm, so that the liquid under pressure maybe drawn off into a glass or other receptacle.

My invention is fully illustrated in the accompanying drawings, in which- Figure l is a sectional plan View of one form of duplex apparatus, one end of the same carrying a draft-tube and the other end y adapted to receive the nozzle of a siphon.

Fig. 2 is a similar sectional view showing a Siphon-nozzle connected therewith, one of the valves opened for the admission of the liquid under pressure, and the Siphon-nozzle packed so that no leakage will occur during the passage of said liquid to the siphon. Fig. 3 is a sectional View of the form of the apparatus in which a single valve is used, such apparatus being shown in a vertical position and adapted to be mounted upon a counter or drinking-bar. Fig. 4 is a sectional front elevation of another form of the duplex apparatus in which two distinct casings are employed with single valves arranged in each casing. Fig. 5 is a side view, partly in section, of the form of duplex apparatus shown in Fig. .4; and Fig. 6 is a modification of the form of apparatus shown in Figs. I and 2 in which a movable casing is employed instead of the movable valve-plug.

The apparatus forming the subject of my invention in its duplex form is particularly applicable for use in saioons, cafs, or other places where liquid refreshment is dispensed, and when used in saloons the apparatus is preferably arranged at the back of the bar and may take the place of one of the usual beer-spigots.

The structure Shown in Fig. 3 is particularly applicable for counter use and may be used for iling a siphon or with the addition of a detachable draft-tube for drawing oit the liquid under pressure into an ordinary glass tumbler or other suitable receptacle.

In the drawings herewith, in Figs. 1 and 2, 1 represents a tubular valve-chest having a pipe extension 2 connected therewith, the latter adapted to pass through the usual slate partition 3 at the rear of the bar and communicating with the tank or other receptacle containing the liquid under pressure. Arranged within the tubular valve-chest are the valves 4, controlling the outletl of the liquid under pressure, said valves having hollow stems 5, adapted to suitable openings in the tubular valve-chest. One end of the tubular valve-chest is closed by a -screw-plug 6, and said plug is provided with an opening for the stern of one of the valves 4. Each valve is provided with a gasket 7, made of any suitable material, and these valves are held to their seats S by means of the coiled spring 9. One of said seats 8 is formed on the solid portion of the tubular valve-chest,while the other is carried by the screw-plug 6. Each of the valve-stems 5 is ported at 10, providing for the passage of the liquid when said valves are open, such ports including cross-passages and openings in line with the stem connecting said crosspassages. The ends of the valve-stems 5 are reduced at Il, forming seats for the plates I2, and compressible bushings 13, composed, preferably, of rubber, are interposed between said plates l2 and the ends of the inclosing sleeve or casing I4. The sleeve or casing 14 is capable of endwise movement on the tubular valve-chest, whereby the bushings 13 may be compressed between the ends of the same and the tubular valve-chest, the valves 4 being opened by such operation. To effect the movement of the sleeve 14, the latter is provided with a yoke-piece 15, to

which a handle 16 is pivoted at 17. This han- IDO have a central opening 2l in line with the openings of the sleeve or casing 14, and the nozzle 22 of a siphon is adapted to be inserted in one of said. openings, as shown in Fig. 2. The opposite end of the sleeve or casing has a threaded projection 23, adapted to receive a draft-tube 24, the latter being threaded to correspond with the threaded portion of the projection 23, but having a plain portion to ent-er the opening in the bushing. The end ot the sleeve or casing is closed by a screwplug 25, which has depressions'26 for the reception of the prongs of a suitable key to turn said screw-plug into place. The screw-plug 6 of the tubular valve-chest is also recessed at 27, so that it may be turned into place by the same tool used for turning the screwplug 25.

In Fig. 2 of the drawings I have shown a siphon in position to be filled with the liquid under pressure. The nozzle 22 of said Siphon is fitted into the opening in the end of the sleeve or casing and enters the opening 21 of the bushing 13, these parts being of such size that an initial close fit is provided for. The Valve of the siphon is now opened and kept open while the siphon is illing. By moving the handle 16 in the direction shown in Fig. 2 the casing will be moved in the same direction, and the bushing 13 will be compressed between the end of the casing and the plate I 12, carried by the stem of the valve, packing the end of the Siphon-nozzle. As the bushing is compressed its greatest pressure is exerted upon the plate 12, carried by the valvestem, and the valve is opened, the gasket 7, carried by the same, being moved away from the seat 8, and the port 10 is open for the admission of the liquid under pressure.

In filling siphons in the manner heretofore practiced great difculty has been experienced in displacing the air as the liquid enters, it being necessary toiremove them frequently from the filling apparatus, invert them, so that the inner filling and discharge tube is above the line of liquid therein, and then open the valve of the siphon and permit the discharge of the air, a process known as snifting. With my structure, however, this snifting operation may be effected without removing the sphon from the casing 14.

This operation is as follows: The siphon to be filled is held in the inverted position with the end of its internal tube at the highest point, and its nozzle 22 is then inserted in the opening 2l of the bushing 13. By maintaining the Siphon-valve open all the time and alternately opening and closing the valve of the filling device, the bushing being compressed to pack the Siphon-nozzle and released simultaneously with the opening and closing of the valve, air is permitted to escape during the filling operation and the snifting accomplished without removing the siphon from the device until it has been entirely filled with the liquid under pressure.

In Fig. 3 I have shown a form of the apparatus adapted to carry a loose draft-tube 24a and having a single valve 4a. This structure is practically the same as that shown in Figs. 1 and 2, except that it has a single valve and is arranged in a vertical instead of a horizontal position. The tubular valve-chest l@L has the outlet-pipe 2a from the source of supply screwed into the same, and the valve 4LL is maintained against its seat by means of a spring 9, interposed between theend of said pipe 2a and the valve 4a. The tubular valvechest has an annular depression 20, and hinged to the sleeve or casing at 17a is ahandie 16, having a projection 18a, adapted to pass through an opening 19a in the sleeve or casing and engage the abrupt shoulderformed by the annular depression 20?'. Downward movement of the handle 16a will move the casing 14a, and the parts will be operated in the same manner as has been described with reference to Figs. 1 and 2.

In Figs. 4 and 5 I have shown a modified form of the duplex structure, in which the tubular valve-chest l" is formed integral with the s upply-pipe 2b and has vertically-arranged members in which the valves 4b are arranged. In this structure separate sleeves or casings 14b surround said vertical members of the tubular valve-chest, and the valves are held in place by springs 9b, the latter being retained by the screw-plugs 6b, which close the ends of the vertical members. The handle 16" is pivoted at 17b to a yoke-piece 15b, carried by the supply-pipe 2b, ends of which are adapted to engage pins 2S, carried by the casings 14k. The casings are slotted at 19b for the passage of these arms 18h. The ends of the casings are closed by screw-plugs 25", and these screw-plu gs are so shaped that they may be readily turned into place. This structure is adapted for use as a draft-arm or for lling a siphon. For the latter purpose the compressible bushing 13b is carried in one of the casings. For the draftarm, however, such bushing is not necessary, and in place of the same I prefer to use a section of metallic tubing 29, so that there will be a positive opening of. the valve when the casing is raised. In some instances it may not be necessary to insert the draft-tube, as the discharge isdo'wnward and is usually directed into a glass tumbler or other suitable receptacle.

In Fig. 6 I have shown a modification of the duplex form of the apparatus shown in Figs. 1 and 2, in which the tubular valvechest is adapted to be moved within the sleeve or casing 14c instead 'otA having the sleeve movable. In this form of the structure the tubular valve-chest lc is made in two parts, which are threaded together at 30, and an opening 3l is provided 4at such threaded portion for the passage of the liquid from the supply-pipe 2C. -In this form of apparatus also the pipe 2c is made integral with IOO and has arms 18h, the

recesses in the surface of said valve-chest.

This structure is provided with the valves, bushings, plates, dto., and the whole operated by the handle 16c in the same manner as the device shown in Figs. 1 and 2.
